Multi-frame display method applied to a display device including a curved surface display screen

1. A multi-frame display method applied to a display device including a curved surface display screen, comprising: performing a first detection to detect whether a user applies a bending input that splits the curved surface display screen into a plurality of display surfaces respectively facing different orientations according to a predetermined fold line; when the display surfaces respectively facing different orientations are detected, acquiring a first position information of the predetermined fold line on the curved surface display screen; dividing a display interface of the curved surface display screen into a plurality of first display sub-interfaces according to the first position information, wherein a split screen line of the first display sub-interfaces coincides with the predetermined fold line; performing a second detection to detect whether the user draws a track on one of the first display sub-interfaces to divide the one of the first display sub-interfaces into two second display sub-interfaces; when the track on the one of the first display sub-interfaces is detected, acquiring a second position information of the track in the one of the first display sub-interfaces; dividing the one of the first display sub-interfaces into two second display sub-interfaces according to the second position information, wherein the track is a separating line of the two second display sub-interfaces; acquiring display contents in the first display sub-interfaces or the second display sub-interfaces selected by the user; and displaying the display content selected in the first display sub-interface or the second display sub-interface through the first display sub-interface or the second display sub-interface.

2. The multi-frame display method according to claim 1 , wherein before acquiring the first position information of the predetermined fold line on the curved surface display screen, further comprising: determining whether a multi-screen display function of the curved surface display screen is selected; and when the multi-screen display function of the curved surface display screen is selected, performing the first detection.

3. The multi-frame display method according to claim 1 , wherein the predetermined fold line is a vertical fold line, and the display screen corresponding to the predetermined fold line protrudes from the curved surface display screen.

4. The multi-frame display method according to claim 3 , wherein the step of acquiring the first position information of the predetermined fold line on the curved surface display screen comprises: acquiring a corresponding column pixel unit of the vertical fold line in the curved surface display screen.

5. The multi-frame display method according to claim 1 , wherein the first detection is performed by a sensor.

6. The multi-frame display method according to claim 5 , wherein the sensor is a pressure sensor or a distance sensor.

7. The multi-frame display method according to claim 1 , wherein before the step of acquiring the second position information of the track in the first display sub-interface, further comprising: determining whether a multi-frame display function of the first display sub-interface is selected; and when the multi-frame display function of the first display sub-interface is selected, performing the second detection.

8. The multi-frame display method according to claim 7 , wherein the step of acquiring the second position information of the track in the one of the first display sub-interfaces comprises acquiring a corresponding pixel unit of the track in the one of the first display sub-interfaces.
